Field of view calculator

Calculate the mathematically correct field of view for your racing simulator, based on monitor size and viewing distance.

Why do this? Watch this video by Empty Box for an explanation. Basically it's so things in the game look the same size as they would in real life, allowing you to judge distances better.

Top view: horizontal FoV; side view: vertical FoV.
